Research Interests: connecting microscale mechanism to ecosystem-scale biogeochemical processes
Brief description of current research:
Human activities are altering global carbon (C) and nitrogen (N) cycles at an unprecedented rate. It is unclear how significant changes in global elemental cycles will affect ecosystem functions, such as primary productivity or C storage over the long-term. My research aims to understand how plant-microbe interactions mediate ecosystem-specific responses to global climate change. This research connects microbial processes to ecosystem functions to yield new insights into microbial ecology and elemental cycling.
Research in my laboratory focuses on three main questions:
